Oberon defeated Hawks by one point at Wade Park in round two, thanks to a Steve Lane field goal.

“We want to reverse that result,” the injured play-maker said.

“They’re a tough side, and they’ll be strong and up front over there. It’s bound to be freezing too.

“I think we need to play an up-tempo kind of game. That’s what has won us the last few games I think, is high intensity.”

Along with Mortimer, Hawks will also be without boom forwards Kurt McNamara and Chris Anau (injured) while winger Steve Khatter is also in doubt after picking up a shoulder niggle in last week’s local derby against CYMS.

“We’re also waiting to see what happens with the Astley Cup incident,” Gibbs-O’Neill said.

Orange High School’s Astley Cup rugby league game against Dubbo Senior College was called off early after erupting into an ugly brawl, and CRL chief executive Terry Quinn said on Friday all players, involved in the brawl or not, from the game would be stood down from club duties until further notice.

Two blues’ under 18 stars Deryne McKenzie and Max Wolfson are set to be the main casualties from the incident, the former named in Hawks’ second row and the latter set to play as a reserve.
